Abstract
BACKGROUND The patient selection for optimal adjuvant therapy in gastrointestinal stromal tumors (GISTs) is provided by nomogram based on tumor size, mitotic index, tumor location, and tumor rupture. Although mutational status is not currently used to risk assessment, tumor genotype showed a prognostic influence on natural history and tumor relapse. Innovative measures, such as KIT/PDGFRA-mutant-specific variant allele frequency (VAF) levels detection from next-generation sequencing (NGS), may act as a surrogate of tumor burden and correlate with prognosis and overall survival of patients with GIST, helping the choice for adjuvant treatment. PATIENTS AND METHODS This was a multicenter, hospital-based, retrospective/prospective cohort study to investigate the prognostic role of KIT or PDGFRA-VAF of GIST in patients with radically resected localized disease. In the current manuscript, we present the results from the retrospective phase of the study. RESULTS Two-hundred (200) patients with GIST between 2015 and 2022 afferent to 6 Italian Oncologic Centers in the EURACAN Network were included in the study. The receiver operating characteristic (ROC) curves analysis was used to classify "low" vs. "high" VAF values, further normalized on neoplastic cellularity (nVAF). When RFS between the low and high nVAF groups were compared, patients with GIST with KIT/PDGFRA nVAF > 50% showed less favorable RFS than patients in the group of nVAF ≤ 50% (2-year RFS, 72.6% vs. 93%, respectively; P = .003). The multivariable Cox regression model confirmed these results. In the homogeneous sub-population of intermediate-risk, patients with KIT-mutated GIST, the presence of nVAF >50% was statistically associated with higher disease recurrence. CONCLUSION In our study, we demonstrated that higher nVAF levels were independent predictors of GIST prognosis and survival in localized GIST patients with tumors harboring KIT or PDGFRA mutations. In the cohort of intermediate-risk patients, nVAF could be helpful to improve prognostication and the use of adjuvant imatinib.

Abstract
BACKGROUND The BRCA proteins play a key role in the homologous recombination (HR) pathway. Beyond BRCA1/2, other genes are involved in the HR repair (HRR). Due to the prominent role in the cellular repair process, pathogenic or likely pathogenic variants (PV/LPVs) in HRR genes may cause inadequate DNA damage repair in cardiomyocytes. PATIENTS AND METHODS This was a multicenter, hospital-based, retrospective cohort study to investigate the heart toxicity from anthracycline-containing regimens (ACRs) in the adjuvant setting of breast cancer (BC) patients carrying germline BRCA PV/LPVs and no-BRCA HRR pathway genes. The left ventricular ejection fraction (LVEF) was assessed using cardiac ultrasound before starting ACR therapy and at subsequent time points according to clinical indications. RESULTS Five hundred and three BC patients were included in the study. We predefined three groups: (i) BRCA cohort; (ii) no-BRCA cohort; (iii) variant of uncertain significance (VUS)/wild-type (WT) cohort. When baseline (T0) and post-ACR (T1) LVEFs between the three cohorts were compared, pre-treatment LVEF values were not different (BRCA1/2 versus HRR-no-BRCA versus VUS/WT cohort). Notably, during monitoring (T1, median 3.4 months), patients carrying BRCA or HRR no-BRCA germline pathogenic or likely pathogenic variants showed a statistically significant reduction of LVEF compared to baseline (T0). To assess the relevance of HRR on the results, we included the analysis of the subgroup of 20 BC patients carrying PV/LPVs in other genes not involved in HRR, such as mismatch repair genes (MUTYH, PMS2, MSH6). Unlike HRR genes, no significant differences in T0-T1 were found in this subgroup of patients. CONCLUSION Our data suggest that deleterious variants in HRR genes, leading to impaired HR, could increase the sensitivity of cardiomyocytes to ACR in early BC patients. In this subgroup of patients, other measurements, such as the global longitudinal strain, and a more in-depth assessment of risk factors may be proposed in the future to optimize cardiovascular risk management and improve long-term survival.

Abstract
Specific tumor-derived extracellular vesicles, called exosomes, are considered as potential key players in cross-talk between immune system and tumor microenvironment in several solid tumors. Different studies highlighted the clinical relevance of exosomes in ovarian cancer (OC) for their role in early diagnosis, prognosis, chemoresistance, targeted therapy. The exosomes are nanosize vesicles carrying lipids, proteins, and nucleic acids. In particular, exosomes shuttle a wide spectrum of microRNAs (miRNAs) able to induce phenotypic reprogramming of target cells, contributing to tumor progression. In this review, we will discuss the promising role of miRNAs shuttled by exosomes, called exosomal miRNAs (exo-miRNAs), as potential biomarkers for early detection, tumour progression and metastasis, prognosis, and response to therapy in OC women, in order to search for new potential biological fingerprints able to better characterize the evolution of this malignancy and provide a clinically relevant non-invasive approach useful for adopting, in future, personalized therapeutic strategies.

Abstract
Breast cancer susceptibility gene 1 (BRCA1) and breast cancer susceptibility gene 2 (BRCA2) deleterious variants were the first and, still today, the main biomarkers of poly(ADP)ribose polymerase (PARP)-inhibitors (PARPis) benefit. The recent, increased, numbers of individuals referred for counseling and multigene panel testing, and the remarkable expansion of approved PARPis, not restricted to BRCA1/BRCA2-Pathogenic Variants (PVs), produced a strong clinical need for non-BRCA biomarkers. Significant limitations of the current testing and assays exist. The different approaches that identify the causes of Homologous Recombination Deficiency (HRD), such as the germline and somatic Homologous Recombination Repair (HRR) gene PVs, the testing showing its consequences, such as the genomic scars, or the novel functional assays such as the RAD51 foci testing, are not interchangeable, and should not be considered as substitutes for each other in clinical practice for guiding use of PARPi in non-BRCA, HRD-associated tumors. Today, the deeper knowledge on the significant relationship among all proteins involved in the HRR, not limited to BRCA, expands the possibility of a successful non-BRCA, HRD-PARPi synthetic lethality and, at the same time, reinforces the need for enhanced definition of HRD biomarkers predicting the magnitude of PARPi benefit.

Abstract
Germline BRCA1/2 alterations in the Homologous Recombination (HR) pathway are considered as main susceptibility biomarkers to Hereditary Breast and Ovarian Cancers (HBOC). The modern molecular biology technologies allowed to characterize germline and somatic BRCA1/2 alterations in several malignancies, broadening the landscape of BRCA1/2-alterated tumors. In the last years, BRCA genetic testing, beyond the preventive value, also assumed a predictive and prognostic significance for patient management. The approval of molecules with agnostic indication is leading to a new clinical model, defined "mutational". Among these drugs, the Poly (ADP)-Ribose Polymerase inhibitors (PARPi) for BRCA1/2-deficient tumors were widely studied leading to increasing therapeutic implications. In this Review we provided an overview of the main clinical studies describing the association between BRCA-mutated tumors and PARPi response, focusing on the controversial evidence about the potential agnostic indication based on BRCA1/2 alterations in several solid tumors.

Abstract
BACKGROUND The most common subtype of ovarian cancer (OC) showing immunogenic potential is represented by the high-grade serous ovarian cancer (HGSOC), which is characterized by the presence of tumor-infiltrating immune cells able to modulate immune response. Because several studies showed a close correlation between OC patient's clinical outcome and expression of programmed cell death protein-1 or its ligand (PD-1/PD-L1), the aim of our study was to investigate if plasma levels of immunomodulatory proteins may predict prognosis of advanced HGSOC women. PATIENTS AND METHODS Through specific ELISA tests, we analyzed plasma concentrations of PD-L1, PD-1, butyrophilin sub-family 3A/CD277 receptor (BTN3A1), pan-BTN3As, butyrophilin sub-family 2 member A1 (BTN2A1), and B- and T-lymphocyte attenuator (BTLA) in one hundred patients affected by advanced HGSOC, before surgery and therapy. The Kaplan-Meier method was used to generate the survival curves, while univariate and multivariate analysis were performed using Cox proportional hazard regression models. RESULTS For each analyzed circulating biomarker, advanced HGSOC women were discriminated based on long (≥ 30 months) versus short progression-free survival (PFS < 30 months). The concentration cut-offs, obtained by receiver operating characteristic (ROC) analysis, allowed to observe that poor clinical outcome and median PFS ranging between 6 and 16 months were associated with higher baseline levels of PD-L1 (> 0.42 ng/mL), PD-1 (> 2.48 ng/mL), BTN3A1 (> 4.75 ng/mL), pan-BTN3As (> 13.06 ng/mL), BTN2A1 (> 5.59 ng/mL) and BTLA (> 2.78 ng/mL). Furthermore, a lower median PFS was associated with peritoneal carcinomatosis, age at diagnosis > 60 years or Body Mass Index (BMI) > 25. A multivariate analysis also suggested that plasma concentrations of PD-L1 ≤ 0.42 ng/mL (HR: 2.23; 95% CI: 1.34 to 3.73; p = 0.002), age at diagnosis ≤ 60 years (HR: 1.70; 95% CI: 1.07 to 2.70; p = 0.024) and absence of peritoneal carcinomatosis (HR: 1.87; 95% CI: 1.23 to 2.85; p = 0.003) were significant prognostic marker for a longer PFS in advanced HGSOC patients. CONCLUSIONS The identification of high-risk HGSOC women could be improved through determination of the plasma PD-L1, PD-1, BTN3A1, pan-BTN3As, BTN2A1 and BTLA levels.

Abstract
Individual response to immune checkpoint inhibitors (ICIs) is currently unpredictable in patients with melanoma. Recent findings highlight a striking improvement in the clinical outcomes of overweight/obese patients treated with ICIs, which seems driven, at least in part, by programmed cell death protein 1 (PD-1)-mediated T-cell dysfunction. A putative role of butyrophilins (BTNs) is under investigation as a novel mechanism of cancer immune evasion and obesity-associated inflammation. This study investigates the role of baseline plasma levels of soluble PD-1 (sPD-1), soluble programmed cell death ligand 1 (sPD-L1), BTN2A1 (sBTN2A1), BTN3A1 (sBTN3A1), along with body mass index (BMI), as predictive biomarkers of immunotherapy response in metastatic melanoma patients treated with nivolumab or pembrolizumab as first-line treatment. In all, 41 patients were included in the study. The baseline plasma level of sPD-1 was significantly lower, and the sBTN2A1 was significantly higher, in long-responder patients to nivolumab or pembrolizumab (median sPD-1: 10.3 ng/ml versus 16.6 ng/ml, p = 0.001; median sBTN2A1: 4.4 ng/ml versus 3.77 ng/ml, p = 0.004). Lower levels of sPD-1 and higher levels of sBTN2A1 were also significantly associated with better overall response rate. Notably, when we further stratified the study cohort using BMI along with sPD-1, patients with BMI ⩾ 25 and sPD-1 < 11.24 ng/ml had longer time to treatment failure after PD-1 inhibitor than other subgroups of patients (p < 0.001). Circulating sPD-1 and sBTN2A1 detection, along with BMI, could give more insights into the immune-metabolic interactions underlying the benefit observed in overweight/obese patients, improving the use of dynamic, noninvasive, biomarkers for patient selection.

Abstract
Background Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer, associated with a worse prognosis. The Immune Checkpoint Inhibitors (ICIs) avelumab and pembrolizumab have been recently approved as first-line treatment in metastatic MCC (mMCC). The clinical observation of improved outcomes in obese patients following treatment with ICIs, known as the "obesity paradox", has been studied across many types of tumors. Probably due to the rarity of this tumor, data on mMMC patients are lacking. Patients and methods This is an observational, hospital-based, study to investigate the role of Body Mass Index (BMI) as predictive biomarker of ICI response in mMCC patients treated with avelumab as first-line treatment. The study population included the patients treated from February 2019 to October 2022 in an Italian referral center for rare tumors. Clinico-pathological characteristics, BMI, laboratory parameters (NLR and platelet count), and response to avelumab were analyzed from a MCC System database prospectively collected. Results Thirty-two (32) patients were included. Notably, the presence of pre-treatment BMI ≥ 30 was significantly associated with longer PFS [BMI < 30 Group: median PFS, 4 months (95% CI: 2.5-5.4); BMI ≥ 30 Group: median PFS, not reached; p<0.001)[. Additionally, the median PFS was significantly higher in patients with higher PLT (median PFS: 10 months in the "low PLT" Group (95% CI: 4.9, 16.1) vs 33 months (95% CI: 24.3, 43.2) in the "high PLT" Group (p=0.006). The multivariable Cox regression model confirmed these results. Conclusion To our knowledge, this is the first study that investigates the predictive role of BMI in MCC patients. Our data were consistent with the clinical observation of improved outcomes in obese patients across other tumor types. Thus, advanced age, a weakened immune system, and the obesity-associated "inflammaging", are key factors that could impact the cancer immune responses of mMCC patients.

Abstract
The most common subtype of ovarian cancer (OC) is the high-grade serous ovarian carcinoma (HGSOC), accounting for 70%–80% of all OC deaths. Although HGSOC is a potentially immunogenic tumor, clinical studies assessing the effectiveness of inhibitors of programmed death protein and its ligand (PD-1/PD-L1) in OC patients so far showed only response rates <15%. However, recent studies revealed an interesting prognostic role of plasma PD-1/PD-L1 and other circulating immunoregulatory molecules, such as the B- and T-lymphocyte attenuator (BTLA), butyrophilin sub-family 3A/CD277 receptors (BTN3A), and butyrophilin sub-family 2 member A1 (BTN2A1), in several solid tumors. Since evidence showed the prognostic relevance of pretreatment serum CA125 levels in OC, the aim of our study was to investigate if soluble forms of inhibitory immune checkpoints can enhance prognostic power of CA125 in advanced HGSOC women. Using specific ELISA tests, we examined the circulating PD-1, PD-L1, pan-BTN3As, BTN3A1, BTN2A1, and BTLA levels in 100 advanced HGSOC patients before treatment, correlating them with baseline serum CA125, age at diagnosis, body mass index (BMI), and peritoneal carcinomatosis. A multivariate analysis revealed that plasma BTN3A1 ≤4.75 ng/ml (HR, 1.94; 95% CI, 1.23–3.07; p=0.004), age at diagnosis ≤60 years (HR, 1.65; 95% CI, 1.05–2.59; p=0.03) and absence of peritoneal carcinomatosis (HR, 2.65; 95% CI, 1.66–4.22; p<0.0001) were independent prognostic factors for a longer progression-free survival (PFS) (≥30 months) in advanced HGSOC women. However, further two-factor multivariate analyses highlighted that baseline serum CA125 levels >401 U/ml and each soluble protein above respective concentration cutoff were covariates associated with shorter PFS (<30 months) and unfavorable clinical outcome, suggesting that contemporary measurement of both biomarkers than CA125 only could strengthen prognostic power of serum CA125 in predicting PFS of advanced HGSOC women. Plasma PD-L1, PD-1, BTN3A1, pan-sBTN3As, BTN2A1, or BTLA levels could be helpful biomarkers to increase prognostic value of CA125.

Abstract
e21525 Background: Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer, associated with a worse prognosis. The link between MCC and immune suppression is well demonstrated. The population of patients with MCC is frequently elderly and frail, making it essential to determine whether the results of clinical trial can be replicated in a real-world setting. Despite the introduction of immune-checkpoint inhibitors (ICIs) has provided great benefit for some patients with advanced MCC (aMCC), it remains a subsets of patients who are refractory to ICIs or develop acquired resistance over time. Thus, there is a clinical need for predictive factors of ICI response. Methods: Twenty patients with aMCC treated with avelumab were included. The treatment was administered as I or II line. Clinical-pathological characteristics, Body Mass Index (BMI), and response to avelumab were analyzed from a MCC System database prospectively collected. An explorative analysis was performed, for available samples, to investigate: i) the plasma levels of soluble PD-1 (sPD-1), and PD-L1 (sPD-L1) collected at baseline, measured using homemade ELISA assays not yet commercially available, and designed according to investigator specifications; ii) IHC for PD-L1 in tumor samples; iii) the presence/absence/class (brisk vs no-brisk) of tumor-infiltrating lymphocytes (TILs) in tumor samples. The primary outcome investigated was the Time to Treatment Failure (TTF). Results: From February 2019 to January 2022, twenty (20) patients were included in the study. The median age was 74 (range 56-83); 10 patients were men (50%) and 10 were women (50%). Seventeen (17) patients (85%) were treated with avelumab as I line, and 3 patients (15%) as II line. The overall response rate was 65% (70.6% in I line patients). One (1) patient (5%) had a complete response (CR), 13 patients (65%) partial response (RP), 4 patients (20%) stable disease (SD), and 2 patients (10%) had a progression disease (PD). Overall median TTF was 22 months (95% confidence interval [CI]: -13.0-30.9). At the time of data analyses, a total of 9 events (progression or death) occurred (45%). Notably, a BMI ≥ 30 was significantly associated with longer TTF (p = 0.004) and objective response rate (p = 0.01). In the explorative biomarker analysis, preliminary data on 6 tumor and plasma samples, showed that plasma sPD-1 > 3.8 ng/ml, and the presence of PD-L1 and brisk TILs on tumor samples, were associated to longer TTF. Conclusions: These finding highlight the complex immune-metabolic interplay in the immunotherapy response. These data extends the previous finding on “obesity paradox” and the role of BMI as predictive factors of ICIs. The data on biomarker analysis warrants further prospective validation.

Following the technological progress and deeper knowledge on BRCA-related cancers, the demand for genetic testing is rapidly increasing. Beyond BRCA1/2, other genes are involved in the HRR, including ATM, PALB2, RAD51, and BARD1. Due to the important role in the cellular repair process, deleterious variants in HRR genes may cause inadequate DNA damage repair in cardiomyocytes. The role of BRCA1/2 as predisposing condition to cardiac dysfunction is debated, and the contribution by no- BRCA genes is still unknown. Methods: This is a multicenter, retrospective, study to investigate the risk of heart-insults from anthracyclines on adjuvant setting in BC patients carrying germline pathogenic or likely pathogenic variant (PV) (classes IV and V) in BRCA and no- BRCA HRR pathway genes. We collected genetic and clinical data, and evaluated the left ventricular ejection fraction (LVEF) at cardiac ultrasound, before starting ACR therapy, and at subsequent time points, according to clinical indications. Results: Three hundred and sixty (360) BC patients, aging 22 to 80, were included in this study; 131 patients were carriers of germline PVs in HRR pathway genes: 52 in BRCA1 gene (39.7%), 48 in BRCA2 gene (36.6%), and 31 harbored PVs in no- BRCA HRR pathway genes (23.7%), including PVs in PALB2, CHEK2, ATM, RAD51C, RAD50 and BARD1 genes. In the cohort of 229 patients without PVs, 47 showed variant of uncertain significance (VUS, class III), and 173 had genetic testing not informative. When LVEF between the groups was compared, the difference was not significant for the pre-treatment values. Notably, individuals carrying BRCA or other HRR gene deleterious variants, showed a statistically significant reduction of LVEF > 5% at the second time-point (3 month), compared to the LVEF pre-treatment values (p = 0.001). A marked LVEF reduction was in mutated patients treated with risk-reducing bilateral salpingo-oophorectomy prior to age 40, body mass index > 25, and type-II diabetes mellitus. The latter risk factor was probably related to increased risk developing insulin-resistance reported for BRCA-mutated patients. Conclusions: Our data suggest that PVs in BRCA or other genes involved in HRR pathway, can lead to impaired homologous recombination, thus increasing sensitivity of cardiac cells to DNA damaging chemotherapy in BC patients. In this subgroup of patients, other measurements such as the global longitudinal strain (GLS), and a more in-depth assessment of risk factors, could be proposed to optimize cardiovascular risk-management and to improve long-term survival.

Abstract
Lynch syndrome (LS) is an inherited genetic condition associated with increased predisposition to colorectal cancer (CRC) and other tumors and is caused by germline mutations in Mismatch Repair (MMR) or EPCAM genes. The identification of LS carriers is currently based on germline testing of subjects with MMR-deficient (dMMR) tumors or fulfilling clinical criteria, but the most efficient strategies to select patients who should be offered genetic testing are yet not well defined. In order to assess the most suitable selection mode to identify LS-related CRC patients, we retrospectively collected and analyzed all clinical and molecular information of 854 CRC patients, recruited from 2013 to 2021 at the University Hospital Policlinico "P. Giaccone" of Palermo (Italy), 100 of which were selected based on revised Bethesda guidelines, Amsterdam criteria II, or tissue MMR deficiency, and genetically tested for germline variants in LS-susceptibility genes. Our study showed that 32 out of 100 CRC patients harbored germline likely pathogenic/pathogenic variants in MMR genes. The analysis of tissue microsatellite instability (MSI) status according to the revised Bethesda guidelines has been to be the best selection approach. However, using different selection approaches as complementary strategies is useful to identify LS carriers, reducing underdiagnosis of this syndrome.

Abstract
Hereditary breast and ovarian cancer syndrome is caused by germline mutations in BRCA1/2 genes. These genes are very large and their mutations are heterogeneous and scattered throughout the coding sequence. In addition to the above-mentioned mutations, variants of uncertain/unknown significance (VUSs) have been identified in BRCA genes, which make more difficult the clinical management of the patient and risk assessment. In the last decades, several laboratories have developed different databases that contain more than 2000 variants for the two genes and integrated strategies which include multifactorial prediction models based on direct and indirect genetic evidence, to classify the VUS and attribute them a clinical significance associated with a deleterious, high-low or neutral risk. This review provides a comprehensive overview of literature studies concerning the VUSs, in order to assess their impact on the population and provide new insight for the appropriate patient management in clinical practice.

Abstract
Alterations in short-repetitive DNA sequences, known as microsatellite instability (MSI), can reflect deficiencies in Mismatch Repair (MMR) system which represents a major player in DNA integrity maintenance. The incidence of MSI-H/dMMR has been shown to be variable depending on the tumor type. Several studies confirmed that dMMR/MSI status, although less frequent than PD-L1 expression, may better predict response to immune-checkpoint inhibitors (ICIs) in patients with solid tumors. In October 2016, the FDA granted pembrolizumab as breakthrough therapy for the treatment of non-CRC, MSI-H/dMMR tumors, providing, for the first time, a tumor-agnostic indication. In the next future, the tissue-agnostic evaluation of MSI-H/dMMR could become the common denominator for the immunotherapy treatment of patients with different advanced solid tumors, in order to select patient subgroups which may benefit from this therapy. In this Review we provided an overview of the main clinical studies describing the association between MSI-H/dMMR tumors and immunotherapy response.

Abstract
Iusse The strategies adopted during COVID19 emergencies by two different hospitals in the Lazio Region are presented: S. Maria Goretti Hospital (SMGH) directly managed by the ASL Latina, hub and centre of the Emergency Department, and Cristo Re Classified Hospital (CRH), accredited in the territory of the ASL Roma1. Description of the problem SMGH has been identified as COVID19 Intervention Hospital. CRH initially was a No-COVID support structure, then included in the COVID19 network. During the COVID19 emergency, the directors of both hospitals had to simultaneously ensure activity as usual, COVID19 recovery and risk management. Results SMGH, while continuing the emergency, oncological, pregnancy, paediatrics and outpatient activities, COVID19 patients was isolated on 7 different floors/areas. Moreover was defined: chain of command; clinical admission criteria; COVID19 multi-professional and support teams, roles, skills and specific training; health surveillance; environmental hygiene, safety paths/procedures, vaccinal center and much more. CRH, while continuing minimum programmed activities to reduce waiting lists, in the first epidemic phase was created 4 tensile structures for Pre-triage and COVID pathways, respiratory isolation area for supsected patient; transfer admission for emergency networks, clean-dirty pathway. Moreover in the second phase, was activated beds of COVID19 network and 4 technical beds OBI; the ‘Walk-in' for antigenic testing, with molecular confirmation <24h and infectious counselling; multi-disciplinary and specialist support teams, training courses, health surveillance, vaccinal center and much more. Lessons During COVID19 pandemic, risk management skills linked to the technical-organisational strategy of hospital directors, making it possible to reprogramme their structure in a short period of time with flexibility and resilience of the whole organization. Key messages Specific skills and roles, both hygienic and organizational, are essential to risk management in hospitals during epidemic emergencies. The multidisciplinarity, flexibility and modularity of the hospital structure are the organizational bases in cases of pandemics.

Abstract
Background: Although the gastrointestinal stromal tumor (GIST) genotype is not currently
included in risk-stratification systems, a growing body of evidence shows
that the pathogenic variant (PV) type and codon location hold a strong
prognostic influence on recurrence-free survival (RFS). This information has
particular relevance in the adjuvant setting, where an accurate
prognostication could help to better identify high-risk tumors and guide
clinical decision-making. Materials and Methods: Between January 2005 and December 2020, 96 patients with completely resected
GISTs harboring a KIT proto-oncogene receptor tyrosine kinase
(KIT) exon 11 PV were included in the study. We
analyzed the type and codon location of the PV according to
clinicopathological characteristics and clinical outcome; the metastatic
sites in relapsed patients were also investigated. Results: Tumors harboring a KIT exon 11 deletion or
deletion/insertion involving the 557 and/or 558 codons, showed a more
aggressive clinical behavior compared with tumors carrying
deletion/deletion/insertion in other codons, or tumors with
duplication/insertion/single-nucleotide variant (SNV) (7-year RFS: 50%
versus 73.1% versus 88.2%,
respectively; p < 0.001). Notably, among 18 relapsed
patients with 557 and/or 558 deletion or deletion/insertion, 14 patients
(77.8%) harbored deletions simultaneously involving 557 and 558 codons,
while only 4 patients (22.2%) harbored deletions involving only 1 of the
557/558 codons. Thus, when 557 or 558 deletions occurred separately, the
tumor showed a prognostic behavior similar to the GIST carrying deletions
outside the 557/558 position. Remarkably, patients with GISTs stratified as
intermediate risk, but carrying the 557/558 deletion, showed a similar
outcome to the high-risk patients with tumors harboring deletions in codons
other than 557/558, or duplication/insertion/SNV. Conclusion: Our data support the inclusion of the PV type and codon location in routine
risk prediction models, and suggest that intermediate-risk patients whose
GISTs harbor 557/558 deletions may also need to be treated with adjuvant
imatinib like the high-risk patients.

Abstract
BACKGROUND Hereditary breast cancer (BC), ovarian cancer (OC), and pancreatic cancer (PC) are the major BRCA-associated tumours. However, some BRCA1/2-wild-type (wt) patients with a strong personal and/or family history of cancer need a further genetic testing through a multi-gene panel containing other high- and moderate-risk susceptibility genes. PATIENTS AND METHODS Our study was aimed to assess if some BC, OC, or PC patients should be offered multi-gene panel testing, based on well-defined criteria concerning their personal and/or family history of cancer, such as earliness of cancer onset, occurrence of multiple tumours, or presence of at least two or more affected first-degree relatives. For this purpose, 205 out of 915 BC, OC, or PC patients, resulted negative for BRCA1/2 and with significant personal and/or family history of cancer, were genetically tested for germline pathogenic or likely pathogenic variants (PVs/LPVs) in genes different from BRCA1/2. RESULTS Our investigation revealed that 31 (15.1%) out of 205 patients harboured germline PVs/LPVs in no-BRCA genes, including PALB2, CHEK2, ATM, MUTYH, MSH2, and RAD51C. Interestingly, in the absence of an analysis conducted through multi-gene panel, a considerable percentage (15.1%) of PVs/LPVs would have been lost. CONCLUSIONS Providing a multi-gene panel testing to BRCA1/2-wt BC/OC/PC patients with a strong personal and/or family history of cancer could significantly increase the detection rates of germline PVs/LPVs in other cancer predisposition genes beyond BRCA1/2. The use of a multi-gene panel testing could improve the inherited cancer risk estimation and clinical management of patients and unaffected family members.

Abstract
About 10–20% of breast/ovarian (BC/OC) cancer patients undergoing germline BRCA1/2 genetic testing have been shown to harbor Variants of Uncertain Significance (VUSs). Since little is known about the prevalence of germline BRCA1/2 VUS in Southern Italy, our study aimed at describing the spectrum of these variants detected in BC/OC patients in order to improve the identification of potentially high-risk BRCA variants helpful in patient clinical management. Eight hundred and seventy-four BC or OC patients, enrolled from October 2016 to December 2020 at the “Sicilian Regional Center for the Prevention, Diagnosis and Treatment of Rare and Heredo-Familial Tumors” of University Hospital Policlinico “P. Giaccone” of Palermo, were genetically tested for germline BRCA1/2 variants through Next-Generation Sequencing analysis. The mutational screening showed that 639 (73.1%) out of 874 patients were BRCA-w.t., whereas 67 (7.7%) were carriers of germline BRCA1/2 VUSs, and 168 (19.2%) harbored germline BRCA1/2 pathogenic/likely pathogenic variants. Our analysis revealed the presence of 59 different VUSs detected in 67 patients, 46 of which were affected by BC and 21 by OC. Twenty-one (35.6%) out of 59 variants were located on BRCA1 gene, whereas 38 (64.4%) on BRCA2. We detected six alterations in BRCA1 and two in BRCA2 with unclear interpretation of clinical significance. Familial anamnesis of a patient harboring the BRCA1-c.3367G>T suggests for this variant a potential of pathogenicity, therefore it should be carefully investigated. Understanding clinical significance of germline BRCA1/2 VUS could improve, in future, the identification of potentially high-risk variants useful for clinical management of BC or OC patients and family members.

Abstract
e17551 Background: Ovarian cancer (OC) is the 10th tumor occurring in women, it accounts for 30% of all malignant tumor affecting female genital tract in Italy. There are several factors that contribute to OC development; in 15-25% of cases family history of breast and ovarian cancer represent the main risk factor. It is well known that pathogenic variants (PVs) occurring in BRCA1/2 genes strongly increase the risk of developing OC, ranging from 50% in BRCA1 PVs carriers to 30% in BRCA2 PVs carriers. Recently genetic polymorphism has been shown to increase cancer risk, consequently polymorphisms in BRCA1/2 genes could represent low penetrance susceptibility alleles and contribute to determine specific clinicopathological features in OC patients harboring BRCA1/2 PVs. Methods: From 2015 to 2021, 338 patients diagnosed with epithelial OC (not mucinous, not borderline) were subjected to BRCA1/2 analysis. After obtaining informed consent, blood samples were processed for genomic DNA isolation; DNA was used for library preparation with the BRaCa Screen kit. Sequencing was performed on the IonS5 platform; variant annotation was performed with Amplicon Suite software. We collected data of both PVs and polymorphisms in BRCA1/2 genes with the aim to evaluate whether a cluster of specific polymorphisms could impact clinicopathological features in BRCA1 PVs carriers. Results: Among the 338 screened EOC, BRCA1/2 PVs were reported in 85 patients (25%). 66% of patients harbored BRCA1 PVs and 34% in BRCA2. The most frequent BRCA1 PVs were the c.4964_4982del (5083del19), c.514delC and c.181T > G; the first and the last are known for their founder effect in Italy and Eastern Europe. Looking at BRCA1 gene, in 75% of patients we identified a polymorphisms cluster (c.2082C > T, c.2311T > C, c.2612C > T, c.3113A > G, c.3548A > G, c.4308T > C, c.4837A > G). The c.514delC and c.181T > G PVs are always associated with the cluster and two additional polymorphisms, the c.2077G > A and the c.1067A > G respectively. Conversely, the cluster seems not to be associated with the PVs 5083del19. Interestingly in BRCA1-5083del19 PV carriers median age at OC diagnosis was 50 years (range 45-69). On average, these patients developed ovarian cancer 6 years earlier than other BRCA1 PV carriers (median age at diagnosis 57 years; range 30-81). Bilateral tumors were frequent and occurred in 57% of the patients versus 33% in OC patients carrying other BRCA1 PVs. Therefore, it seems that the cluster has a “protective” effect and that its absence reduces age at diagnosis. Conclusions: Despite this study has the main limitation of a small sample size, we have reported a possible association between polymorphisms cluster and clinicopathological features in BRCA1 PVs carriers. By further investigating this aspect in a larger cohort, we might be able to prove the role of this cluster in increasing or reducing OC risk and providing clinicians more information useful for patients’ stratification.

Abstract
The HIPPO pathway (HP) is a highly conserved kinase cascade that affects organ size by regulating proliferation, cell survival and differentiation. Discovered in Drosophila melanogaster to early 2000, it immediately opened wide frontiers in the field of research. Over the last years the field of knowledge on HP is quickly expanding and it is thought will offer many answers on complex pathologies. Here, we summarized the results of several studies that have investigated HP signaling both in oncology than in cardiology field, with an overview on future perspectives in cardiology research.

Abstract
Background Several available data suggest the association between specific molecular subtypes and BRCA1/2 mutational status. Previous investigations showed the association between BRCA1/2 pathogenic variants (PVs) in specific genomic regions and phenotypic variations of cancer relative risk, while the role of PV type and location in determining the breast cancer (BC) phenotypic features remains still unclear. The aim of this research was to describe the germline BRCA1/2 PVs in triple-negative breast cancer (TNBC) versus luminal-like BC and their potential leverage on BC phenotype. Patients & methods We retrospectively collected and analyzed all clinical information of 531 patients with BC genetically tested for germline BRCA1/2 PVs by Next-Generation Sequencing analysis at University Hospital Policlinico "P. Giaccone" of Palermo (Sicily) from January 2016 to February 2020. Results Our results corroborate the evidence that BRCA1-related tumors often have a profile which resembles the TNBC subtype, whereas BRCA2-associated tumors have a profile that resembles luminal-like BC, especially the Luminal B subtype. Interestingly, our findings suggest that the PVs identified in TNBC were not largely overlapping with those in luminal-like tumors. Differences in the frequency of two PVs potentially associated with different molecular tumor subtypes were observed. BRCA1-633delC was detected with relatively higher prevalence in patients with TNBC, whereas BRCA2-1466delT was found mainly in Luminal B tumors, but in no TNBC patient. Conclusion Future studies examining the type and location of BRCA1/2 PVs within different molecular subtypes are required to verify our hypothesis and could provide an interesting insight into the complex topic of genotype-phenotype correlations. Additionally, a more in-depth understanding of the potential correlations between BRCA PVs and clinical and phenotypic features of hereditary BC syndrome patients could be the key to develop better strategies of prevention and surveillance in BRCA-positive carriers without disease.

Abstract
Despite a proportion of renal cancer patients can experiment marked and durable responses to immune-checkpoint inhibitors, the treatment efficacy is widely variable and identifying the patient who will benefit from immunotherapy remains an issue. We performed a prospective study to investigate if soluble forms of the immune-checkpoints PD-1 (sPD-1), PD-L1 (sPD-L1), pan-BTN3As, BTN3A1, and BTN2A1, could be candidate to predict the response to immune-checkpoint blockade therapy. We evaluated the plasma levels in a learning cohort of metastatic clear cell renal carcinoma (mccRCC) patients treated with the anti-PD-1 agent nivolumab by ad hoc developed ELISA’s. Using specific cut-offs determined through ROC curves, we showed that high baseline levels of sPD-1 (>2.11 ng/ml), sPD-L1 (>0.66 ng/ml), and sBTN3A1 (>6.84 ng/ml) were associated with a longer progression-free survival (PFS) to nivolumab treatment [median PFS, levels above thresholds: sPD-1, 20.7 months (p < .0001); sPD-L1, 19 months (p < .0001); sBTN3A1, 17.5 months (p = .002)]. High sPD-1 and sBTN3A1 levels were also associated with best overall response by RECIST and objective response of >20%. The results were confirmed in a validation cohort of 20 mccRCC patients. The analysis of plasma dynamic changes after nivolumab showed a statistically significant decrease of sPD-1 after 2 cycles (Day 28) in the long-responder patients. Our study revealed that the plasma levels of sPD-1, sPD-L1, and sBTN3A1 can predict response to nivolumab, discriminating responders from non-responders already at therapy baseline, with the advantages of non-invasive sample collection and real-time monitoring that allow to evaluate the dynamic changes during cancer evolution and treatment.

Abstract
Pompe disease (PD) is a rare autosomal recessive disorder caused by mutations in the GAA gene, localized on chromosome 17 and encoding for acid alpha-1,4-glucosidase (GAA). Currently, more than 560 mutations spread throughout GAA gene have been reported. GAA catalyzes the hydrolysis of α-1,4 and α-1,6-glucosidic bonds of glycogen and its deficiency leads to lysosomal storage of glycogen in several tissues, particularly in muscle. PD is a chronic and progressive pathology usually characterized by limb-girdle muscle weakness and respiratory failure. PD is classified as infantile and childhood/adult forms. PD patients exhibit a multisystemic manifestation that depends on age of onset. Early diagnosis is essential to prevent or reduce the irreversible organ damage associated with PD progression. Here, we make an overview of PD focusing on pathogenesis, clinical phenotypes, molecular genetics, diagnosis, therapies, autophagy and the role of miRNAs as potential biomarkers for PD.

Abstract
Viper venom disintegrins have been used frequently to study the cellular receptors which characterize various types of cells, including platelets, endothelial cells and cancer cells. While the majority of such analyses have pointed to involvement of integrin receptors alphavbeta3, alpha5beta1 or alphaIIbbeta3, this may not always be so. Eristostatin, from Eristocophis macmahoni, is a potent inhibitor of ADP-induced platelet aggregation as well as of human and murine melanoma metastases in mouse model systems. This disintegrin requires an RGDW motif, as well as an intact C-terminus, in order to interact with both platelets and four different types of melanoma cells. Eristostatin causes nonmetastatic SBc12 melanoma cells to show higher susceptibility to specific killing by NK-like TALL-104 cells. While it is known that eristostatin binds to alphaIIbbeta3 on platelets, the receptor with which eristostatin binds to the melanoma cells has not yet been identified.

Abstract
The venom of Echis carinatus suchoreki contains a monomeric disintegrin echistatin (Mr 5,500 Da) that strongly inhibits alphaIIbbeta3, alphavbeta3, and alpha5beta1 integrins and a heterodimeric disintegrin called EC3 (M(r) 14,762 Da). At nanomolar concentration, EC3 inhibits adhesion of human cell lines expressing alpha4beta1 and alpha4beta7 to immobilized VCAM-1; it has a lower inhibitory effect on alpha5beta1-mediated cell adhesion. In this study, we demonstrated that EC3, in contrast to echistatin, inhibited binding of monoclonal anti-alpha4 and anti-alpha5 antibodies to cells expressing alpha4beta7. In a dose-dependent manner and to the same extent, EC3 inhibited adhesion of Jurkat cells and murine splenic lymphocytes to immobilized VCAM-1, whereas echistatin was not active. EC3 injected intraperitoneally into nonobese diabetic (NOD mice) suppressed development of insulitis and sialoadenitis, whereas echistatin had no significant effect. We propose that the effect of EC3 is mediated, at least, in part, by blocking alpha4beta1 and alpha4beta7 on murine lymphocytes.

Abstract
Abstract
The murine vitronectin receptor (VNR, alpha V beta 3) is expressed on T cell hybridomas expressing both the alpha beta and the gamma delta TCR as well as on TCR-alpha beta cells activated for prolonged periods of time by mitogens or alloantigens. The VNR functions as a costimulatory molecule for the activation of a subset of gamma delta T cells that express the V gamma 1.1 C gamma 4 V delta 6 TCR and that may recognize a ubiquitously expressed autoantigen. To characterize further some of the signal transduction parameters observed after engagement of the VNR in stimulated T lymphocytes, we have examined the effect of ligation of the VNR by RGDS-containing proteins on the pattern of protein phosphorylation. We demonstrate the appearance of a 115-kDa, tyrosine-phosphorylated protein (pp115) after engagement of the VNR with its ligand, RGDS. pp115 was shown to be immunologically distinct from focal adhesion kinase, did not possess inherent kinase activity, and may represent an as yet unidentified substrate in the integrin signal transduction pathway. Although induction of pp115 was independent of TCR expression, because it was seen in the TG40 hybridoma, which expresses neither the alpha beta nor the gamma delta TCR, pp115 could also be induced by cross-linking of the TCR in a murine TCR gamma delta hybridoma in the absence of any extracellular matrix proteins. This result raises the possibility that induction of pp115 is a common biochemical step in signal transduction by both the TCR and the VNR.

Abstract
Abstract
The "outside-in" signals produced by the interaction of integrin molecules with the extracellular matrix (ECM) trigger a multitude of cellular events. The vitronectin receptor (VNR), an alpha v beta 3 heterodimer, functions as a costimulatory molecule for the activation of a subset of V gamma 1.1/C gamma 4-bearing gamma/delta T cells, which have been postulated to recognize a ubiquitous self-antigen. We addressed the question of whether stimulation of these T cells requires both engagement of the VNR by ECM proteins and engagement of the TCR by its Ag. We introduced into a TCR- but VNR+ mutant T cell hybridoma, TG40 (derived from 2B4), a chimeric molecule that contains the cytoplasmic tail of the TCR zeta-chain fused to the cytoplasmic and transmembrane region of either human CD8 or human CD25. The transfectants expressing the chimeric molecules secreted IL-2 constitutively when the VNR was engaged with a ligand, e.g., provided by ECM proteins present in FCS. This constitutive cytokine secretion could be blocked with mAb directed against the VNR, with or the peptide RGD, or by growth in serum-free medium. VNR-mediated cell activation also induced the phosphorylation of the zeta-chain. Signaling through the zeta-chain was required, as cells transfected with a chimera containing only a 22 amino-acid long, truncated zeta-chain did not secrete IL-2 constitutively. Thus, we demonstrated that the binding of the VNR to ECM protein in the presence of the zeta-chain is sufficient to induce cytokine secretion by T cells and does not require the recognition of an Ag by the TCR. Such integrin-mediated, Ag-independent activation of T cells may play a critical role in the potentiation of inflammatory responses.

Abstract
Murine T helper cloned cells permeabilized with the bacterial lysin, tetanolysin, were used to investigate the role of intracellular Ca2+ in regulating myo-[2-3H] inositol phospholipid (InsPL) hydrolysis triggered upon perturbation of the T cell receptor-CD3 complex. [Ca2+] was controlled by a calcium/magnesium/EGTA buffer. Antibody (mAb) aggregation of CD3 induced InsPL hydrolysis in the absence of added Ca2+. However, stimulated InsPL hydrolysis increased with the free [Ca2+], reaching a maximum at 100-300 nM [Ca2+]. Ca2+ increased the overall efficiency of hydrolysis without changes in EC50 of the anti-CD3 mAb. The response diminished at > 300 nM [Ca2+] due to a mixed type inhibition. Ca2+ alone had no effect on inositol phosphate levels. Polyphosphoinositides were preferentially cleaved, since no accumulation of Ins(1)P/Ins(3)P was detected, indicating that direct hydrolysis of phosphatidylinositol did not occur, irrespective of the Ca2+ concentration. [Ca2+] above 300 nM shifted the relative amounts of CD3-induced inositol 1,4,5-trisphosphate (Ins(1,4,5)P3) and inositol 1,3,4,5-tetrakisphosphate (Ins(1,3,4,5)P4) in favor of the latter. Unlabeled permeabilized cells exposed to > or = 100 nM [Ca2+] showed enhanced conversion of [3H]Ins(1,4,5)P3 to [3H]Ins(1,3,4,5)P4. In conclusion, InsPL hydrolysis is optimally triggered by CD3 perturbation at intracellular Ca2+ levels approximating those observed in intact resting lymphocytes (100 nM). Ca2+ concentrations similar to those triggered by InsPL-derived metabolites may inhibit InsPL hydrolysis and promote Ins(1,3,4,5)P4 production, thus controlling the amounts of Ins(1,4,5)P3.

Abstract
The CD59 Ag is a 20-kDa protein that is widely expressed on most leukocytes and RBC, is coupled to the membrane by a phosphatidylinositol-glycan anchoring structure, plays a role in cell interaction between monocytes and T cells, and also functions as an inhibitor of cytolysis by the terminal C components C5b-9. Because this molecule is structurally related to the murine Ly-6 family of Ag, we have investigated whether anti-CD59 mAb might be capable of activating human T lymphocytes in a manner similar to that described for antibodies to the murine Ly-6 Ag. In the presence of the appropriate co-stimulators, mAb to one of the two epitopes on CD59 were capable of inducing both a rise in intracytoplasmic free Ca2+, inositol phosphate production, IL-2 production, and T cell proliferation. Anti-CD59-induced inositol phosphate turnover and IL-2 production were dependent on co-expression of the CD3/TCR complex. CD59-loss mutants of the Jurkat cell line were completely responsive to stimulation by anti-CD3 thereby demonstrating that CD59 does not play a role as a signal transducer downstream from the TCR. Taken together, these results demonstrate that the CD59 Ag can play multiple distinct roles in the regulation of the immune response.

Abstract
Perturbation of the T-cell receptor (TCR) complex is followed by the rapid hydrolysis of inositol phospholipids (InsPL) by phospholipase C (PLC), producing diacylglycerol and inositol phosphates, which act as second messengers in signal transduction. The mechanism coupling the TCR to InsPL hydrolysis is not clearly defined, and no information is available on this mechanism in the CD4+ helper subset of T-lymphocytes (Th). We have tested the hypothesis that guanine-nucleotide-binding proteins (G-proteins) may couple the TCR to PLC in a murine Th type II (Th2) cell clone. Cell permeabilization with streptolysin O (SLO) or tetanolysin (TL) was used to allow membrane-impermeable nucleotides access to intracellular sites of action. Exposure of permeabilized Th2 cells to guanosine 5'-[gamma-thio]triphosphate (GTP gamma S), a non-hydrolysable GTP analogue, resulted in a 2.1-2.5-fold increase in inositol phosphate generation. Similarly, perturbation of the TCR with the monoclonal antibody 145.2C11 (directed against the epsilon-chain of the CD3 component of the TCR) resulted in a 3.1-4.2-fold increase in InsPL hydrolysis by permeabilized cells. Both lysins were similarly effective in allowing GTP gamma S induction of InsPL hydrolysis, but TL-permeabilized cells responded better to TCR perturbation than SLO-treated cells. A role for G-proteins in TCR coupling to PLC was further supported by the inhibition of TCR-induced InsPL hydrolysis by guanosine 5'-[beta-thio]diphosphate (GDP beta S), a guanine nucleotide analogue that inhibits G-protein function. ATP was required for TCR-mediated InsPL hydrolysis, and potentiated GTP gamma S-induced hydrolysis. Other nucleotides (i.e. CTP, GDP, GTP, ITP) did not affect the response. These data indicate that G-proteins may contribute to the regulation of PLC activation in Th2 cells, coupling it to the TCR.

Abstract
Human monocytes obtained by counter-current centrifugal elutriation released arachidonic acid when challenged in vitro with Con A, as well as with other soluble (PMA or ionomycin) or particulate stimuli (serum-treated zymosan). Cyclo-oxygenase metabolites were the principal eicosanoids detected in the supernatants of Con A-stimulated, [3H]arachidonate-labeled monocytes, 5-Lipoxygenase (5-LO) products, such as leukotriene B4 (LTB4), were conspicuously absent. Release of arachidonate and its metabolites in response to Con A was dependent on the presence of extracellular Ca2+, but not Mg2+. In contrast to serum-treated zymosan challenge, which resulted in increased inositol trisphosphate and LTB4 release, Con A-induced inositol phospholipid hydrolysis in monocytes was limited to phosphatidylinositol or phosphatidylinositol monophosphate. Despite an inability to augment LTB4 release, Con A or PMA induced a loss of 5-lipoxygenase from a cytosolic compartment that was similar to that achieved with a calcium ionophore (ionomycin), a potent stimulus for LTB4 generation. When cell-associated LTB4 was evaluated, evidence for increased LTB4 production was obtained in response to either stimulus (PMA greater than Con A). In combination, however, PMA and Con A treatment resulted in monocyte LTB4 release comparable with that observed with the calcium ionophore or STZ. LTB4 release in response to all stimuli tested was inhibited by MK-886, a drug that binds to 5-lipoxygenase-activating protein. These results indicate the following: 1) Phospholipase A2 activation and attendant arachidonic acid release induced by agents that increase intracellular Ca2+ and/or generate diacylglycerol results in increased synthesis and release of PG and increased synthesis of leukotrienes, but not necessarily leukotriene release. 2) 5-LO translocation, which may occur independently of increased intracellular Ca2+, may be necessary for LTB4 generation but is insufficient for its release. 3) 5-Lipoxygenase-activating protein activity is necessary for 5-LO activation and LTB4 release in response to all stimuli investigated here. 4) Phorbol ester, an activator of protein kinase C, may synergize with agents such as Con A (which by themselves induce a minimal intracellular Ca2+ rise), so as to result in the release of LTB4. Thus, Con A may represent a class of surface receptor-aggregating agents that initiates inflammatory changes or immunomodulation associated with liberation of PG and might predispose to release of other inflammatory mediators, such as leukotrienes, in the presence of additional signals including protein kinase activation.

Abstract
Surfactants have been employed in high-performance liquid chromatography (HPLC) for the separation of ionic and non-ionic compounds. We have developed a method employing a reversed-phase column and a mobile phase containing a surfactant, hexadecyltrimethylammonium hydroxide (HDTMA+OH-), for the separation of several inositol phosphate positional isomers. Various parameters were studied for their effect on the chromatographic capacity factor (k'). They included the concentration of HDTMA+OH-, the pH of the bulk micellar suspension and the addition of inorganic salts to the mobile phase. Resolution of the inositol monophosphates was controlled by a mixed mechanism, where the predominant elements were electrostatic forces and the formation of micelles. The elution of the inositol polyphosphate isomers was obtained by increasing the amount of a non-polar solvent, in agreement with an ion-pairing process. This method represents an alternative to ion-exchange HPLC. If offers a practical advantage when detection of radiolabeled samples by in-line radioactive flow detectors is required, because low-quenching solvents with good miscibility with scintillant fluids are employed. The analysis of various chromatographic conditions, the system reproducibility and its application to the analysis of biological samples are described.

Abstract
Human monocytes release arachidonic acid upon stimulation with a variety of soluble or particulate agents. These include: phorbol esters (i.e., 12-O-tetradecanoate phorbol-13-acetate, TPA), calcium ionophores (ionomycin), serum-treated zymosan (STZ) concanavalin A (Con A), and, to a minor degree, lipopolysaccharides (LPS). Protein Kinase C activation or increased intracellular Ca2+ are common features of the actions of most, if not all, of these stimuli. Prevention of PKC activation by the use of staurosporine or chelation of extracellular calcium by EGTA selectively impaired AA release, indicating that PLA2 may be regulated by either pathway concurrently. The generation of inositol phosphates and diacylglycerol by the action of phospholipase C, notably upon interaction with opsonized particles during phagocytosis, apparently constitutes the physiological correlate of stimulation via these agents. Release of arachidonic acid by the action of PLA2 or other phospholipid hydrolyzing enzymes leads directly to the formation of cyclooxygenase products. In the presence of markedly elevated calcium concentrations, 5-lipoxygenase (LO) is activated as well, leading to the formation and release of leukotrienes. Agents which stimulate AA release also initiate other monocyte functions, including generation of reactive oxygen intermediates and lymphokine release. This observation makes it tempting to implicate PLA2 activation in many aspects of monocyte physiology. However, no correlation with PLA2 activation and either superoxide or lymphokine release was found when multiple stimuli, including TPA, ionomycin, serum-treated zymosan, concanavalin A, or LPS, were compared simultaneously. Instead, our results indicate that PLA2 activation is regulated by the same mechanisms, including PKC activation and increased Ca2+, as are other enzymes which determine expression of monocyte function. Phospholipase A2 (PLA2) hydrolyzes fatty acid from the sn-2 position of a wide variety of phospholipids. Substrates for this (these) enzyme(s) include species which contain a variety of polar head groups (choline, serine, ethanolamine, etc.) and some phospholipids with either linkages in sn-1. In many cell types, including human monocytes, phospholipase A2 commonly acts on substrates containing arachidonic acid (AA). The liberation of free arachidonate is a first step in the metabolism of prostaglandins, hydroxyeicosatetraeinoic acids, (HETE'S), and leukotrienes (Lt's). Monocytes and macrophages have been shown to be rich sources of arachidonate and its metabolites. Some biologic properties of monocytes, notably their role as immunomodulating cells, have been attributed to eicosanoid production and release. Accordingly, much of the interest regarding PLA2 in human monocytes centers on this aspect of their function.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
Testis structure and functions were monitored in male Wistar rats chronically exposed to various levels of sodium selenite (Na2SeO3) in drinking water (4, 8 or 16 ppm). The most remarkable testicular changes were observed in the 16 ppm group: intertubular oedema, oligospermia, scattered foci of degenerated spermatids were found. In addition, marked changes in several specific enzymes of testicular cells occurred along with a significant reduction of mean-tubular-diameters, mean-tubular-areas and mean-tubular-perimeters. These results clearly demonstrate a testicular involvement during chronic exposure of the rat to selenium.

Abstract
An experimental model for monitoring rat liver function during protracted exposure to hepatotoxic agents is proposed. Owing to their invasiveness, the models usually employed are appropriate for studying the mechanism of action of toxic substances, but do not allow the liver situation to be followed over the course of time. The need to sacrifice animals to determine liver triglycerides-one of the key parameters in the progress of toxic damage- reduces the possibility of following such progress in the same animals. This study describes the testing of a model for monitoring three basic parameters of liver injury: cytolysis, steatosis and metabolic deficiency of the liver. CCl4 has been chosen as model-hepatotoxin. Steatosis is determined by evaluating the triglyceride content of small specimens of liver, obtained through open-field biopsies, which appear to be representative of the whole liver. Fatty liver is paralleled by the block in Triton-induced hypertriglyceridaemia. Determination of serum triglycerides derives from a very poorly invasive technique which can be repeated several times. The combination of these tests with the assessment of both the cytolysis (ALT and SDH release into the circulation) and the impairment of the efficiency of liver microsomal enzymes (TMO clearance), seems to offer a reliable experimental procedure in predicting the hepatotoxic effect of xenobiotics.
